//  This driver provides functions to configure and program the Flash memory of all STM32F10x devices,
//  including the latest STM32F10x_XL density devices. 

//  STM32F10x_XL devices feature up to 1 Mbyte with dual bank architecture for read-while-write (RWW) capability:
//     - bank1: fixed size of 512 Kbytes (256 pages of 2Kbytes each)
//     - bank2: up to 512 Kbytes (up to 256 pages of 2Kbytes each)
//  While other STM32F10x devices features only one bank with memory up to 512 Kbytes.

//  In version V3.3.0, some functions were updated and new ones were added to support
//  STM32F10x_XL devices. Thus some functions manages all devices, while other are 
//  dedicated for XL devices only.
 
//  The table below presents the list of available functions depending on the used STM32F10x devices.
